I think frm the past few days... someone has been using my account.I got an IP coflict message for the whole day. When I checked my logs, it showed activity.I asked one of my friend. He said if the person used my IP and forced my MAC ID, then theres absolutely no way to track him down.Although, he said that if the person had used something like ES1, which lets u login, but doesnt change ur IP or MAC, then it wud hve been possible to track him down.What shud i do.... opt for a new IP. But even if I do, the person can login using ES1. I still can't understand, I had logged out properly, then how did the person use my account.Please advise and tell me if there is any way by which sify can track down this creep .
